The 3-D animated video helps students understand the wordings in a geometry problem. Although the video shows the traditional way to solve the problem, a novel way video only requires free log in. It shows how to develop critical thinking skills to look at the problem in different ways. The video fits the visual learners' style and may reduce the anxiety of students who have difficulty thinking in abstract terms.
